“…Dy 3+ is a good activator for white light emission, because it has strong 4 F 9/2 → 6 H 15/2 (blue light) and 4 F 9/2 → 6 H 15/2 (yellow light) energy level transitions. 147,148 Harpreet Kaur et al 149 prepared Na 2 CaSiO 4 (NCS):Dy 3+ phosphors by the sol–gel method. The emission intensity of the obtained phosphor at 423 K can also be maintained at 77.26% of that at room temperature.…”

“…Due to the 1 d 2 -3 f 4 transition of Tm 3+ , the inorganic compounds doped with Tm 3+ show excellent blue emission energy level transitions. 147,148 Harpreet Kaur et al 149 prepared Na 2 CaSiO 4 (NCS):Dy 3+ phosphors by the sol-gel method. The emission intensity of the obtained phosphor at 423 K can also be maintained at 77.26% of that at room temperature.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
